Today, phishing attacks represent one of the biggest security threats targeting users of the digital world. They consist of an attempt to steal sensitive information, such as a user's identity or credit and debit card details, using various methods that include fake emails, fake websites, and fake social media messages. Protecting the user's security and privacy therefore becomes complex, especially when those users are children. Currently, children are participating in Internet activity more frequently than ever before. This activity includes, for example, online gaming, communication, and schoolwork. However, children tend to have a less well-developed knowledge of privacy and security concepts, compared to adults. Consequently, they often become victims of cybercrime. In this paper, the effects of security awareness on users who are children are investigated, looking at their ability to detect phishing attacks in social media. In this approach, two Experiments were conducted to evaluate the effects of security awareness on WhatsApp application users in their daily communication. The results of the Experiments revealed that phishing awareness training has a significant positive effect on the ability of children using WhatsApp to identify phishing messages and thereby avoid attacks.

This study aims to evaluate some academic institutional repositories (IRs) in Ghana. Data were collected using observation and interview methods by examining the various websites of seven (7) selected academic institutional repositories in Ghana. The findings revealed that the University of Ghana, Legon, leads records count of the seven Institutional Repository (IRs) examined. Dspace was the prioritized software for managing and preserving the digital contents of these IRs. Theses, dissertations and research articles were the leading contents deposited on the IRs. The majority of the IRs have incorporated RSS (Rich Site Summary or Really Simple Syndication) feeds on their IRs with few using other Web 2.0 features. English was the only interface language used on all the IRs. From the interview, the findings revealed that most of the faculty members did not use the IR very often and 9(42.9) also indicated that, they have never deposited their materials on the IR. Faculty members again indicated that, inadequate ICT connectivity and infrastructure, unreliable power supply, Copyrights and intellectual rights, financial constrain, inadequate advocacy and training on the importance of IRs to faculty and users were the major challenges of academic libraries in operating IRs in Ghana.

The current study examined the influence of individual trait such as Need-For-Touch level (NFT; high vs. low) and swiping orientation (vertical vs. horizontal) on product evaluation and preference when using touch-screen interface like a smart phone and a tablet. Swiping is one of the most common interaction techniques for changing pages or searching some aligned pictures on touch-screen interface and it can be used in vertical and horizontal orientations. The experiment revealed a significant interaction between swiping orientation and NFT on preference, however the interaction on change-in-price of given products was only marginally significant. To be specific, high NFT participants reported higher preference for horizontal-swipe than vertical-swipe products, but such difference did not occur with low NFT participants. The current study illustrates the influence of swiping orientation and NFT on product preference and it provides a new perspective of design principles especially for online shopping websites.

The purpose of this study is to examine the compensatory role of instrumental (e.g., product information) and aesthetic (e.g., website background) online cues presented within apparel websites where touch is unavailable. The moderating role of two need for touch (NFT) dimensions (i.e., autotelic and instrumental NFT) between online cues and consumer responses was also investigated. Results demonstrate that personal differences in autotelic and instrumental NFT moderate the relationship between online cues and affective responses. It was found that consumers high in autotelic NFT (i.e., who need to touch for fun) seek more instrumental cues to compensate for lack of touch when shopping apparel products online. Surprisingly, consumers high in instrumental NFT (i.e., who need to touch for product evaluation) use aesthetic as well as instrumental cues to supplement the absence of touch. In contrast, for the low NFT groups, only aesthetic online cues showed significant effects on consumer arousal. Further analysis shows that instrumental NFT is negatively related to purchase intention while autotelic NFT has a positive effect on purchase intention. This implies that need for hedonic-oriented touch is no longer a barrier for online apparel shopping. However, the instrumental NFT seems a significant obstacle for the adoption of online apparel purchasing.

웹 사용성(Web usability)은 웹 사이트 이용자가 원하는 목표를 보다 쉽게 달성하도록 시스템을 설계하는 것으로 이용의 편이성을 말한다. 본 연구에서는 국내 의료기관 웹 사이트를 대상으로 사용성 평가를 실시하고 그 결과를 분석하였다. 의료기관을 종합병원, 대학병원, 일반병원 3개의 그룹으로 나누고 각 그룹에서 4개씩 총 12개 병원을 선정하여 평가하였으며, 사용성 평가를 위해 평가 전설문지, 태스크 수행 평가, 평가 후 설문지 그리고 평가자 인터뷰를 실시하였다. 설문지 결과와 인터뷰 결과를 볼 때, 대다수의 병원들이 예약과 취소, 정보검색 등 웹 서비스 제공에 노력을 기울이고 있지만 실제 사용자는 병원의 주요 서비스를 이용하는데 있어서 편리하다고 느끼지 않는 것으로 조사되었다. 태스크 수행 평가 결과를 살펴보면, 대학병원은 다른 그룹과 비교해 볼 때 비교적 사용성을 고려하여 잘 설계되었으나 서비스 절차의 단순화 작업이 필요하다고 판단되며, 일반병원의 경우 태스크 수행과 관련된 서비스 자체가 제공되지 않거나 체계적이지 못한 경우가 있어 개선이 필요하였다.
